Abstract (en)
[origin: WO9720130A2] Downhole apparatus is disclosed for use in expanding liner or tubing. The apparatus (10) comprises a body (12) for connection to a string (14) and an expansion portion on the body, the expansion portion including a plurality of radially movable parts (16, 17) for defining an outer surface thereof. The parts (16, 17) are initially arranged in an axially and circumferentially offset first configuration (Figure 1) in which the parts may assume a smaller diameter first configuration. The apparatus (10) is then run into a borehole and through a length of expandable tubing (18). The parts (16, 17) are then moved radially outwardly and axially aligned such that the parts assume a larger diameter second configuration and define a substantially continuous outer circumference (Figure 2). The expansion portion is then pulled through the tubing to expand the tubing (18).
